Abstract

fetched live from OpenAlex

Ce mémoire aborde trois des principaux aspects de la problématique associée à la robotique mobile: la perception de l'environnement, la représentation virtuelle de l'environnement et la planification de trajectoire. Plus spécifiquement, ces trois aspects sont considérés pour un robot marcheur. Puisque les capacités de déplacement supplémentaires de ce robot sont directement associées au relief du sol, les éléments présentés dans ce mémoire considèrent uniquement la topographie du terrain se trouvant devant le robot. \n \nPour la première partie, on présente de façon détaillée la conception et le développement d'un capteur basé sur un système de vision stéréoscopique binoculaire actif. La deuxième partie présente une méthode de représentation virtuelle de l'environnement de type surface d'élévation. Enfin, la troisième partie présente l'implantation d'un algorithme de planification de trajectoire basé sur la méthode conventionnelle suivant les contours d'obstacles polygonaux. Finalement, on présente plusieurs résultats de simulation permettant d'évaluer la performance globale des systèmes développés. \n \n

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
